CVE-2026-60306: Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core).
Vulnerability in the Oracle Coherence product of Oracle Fusion Middleware (component: Core). Supported versions that are affected are 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0 and 15.1.1.0.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via TCP to compromise Oracle Coherence. Successful attacks of this vulnerability can result in takeover of Oracle Coherence. CVSS 3.1 Base Score 9.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
Security readout for executives and security teams
Plain-English summary
This is a critical Oracle Coherence flaw. An attacker who can reach the service over TCP may compromise it without credentials or user interaction. Oracle says successful exploitation can lead to takeover of Oracle Coherence, creating serious confidentiality, integrity, and availability risk.
Executive priority
Treat as urgent. The combination of unauthenticated network reachability, low attack complexity, and potential takeover justifies rapid inventory, exposure reduction, and vendor-guided remediation.
Technical view
CVE-2026-60306 affects Oracle Coherence Core in versions 12.2.1.4.0, 14.1.1.0.0, 14.1.2.0.0, and 15.1.1.0.0. CVSS 3.1 is 9.8: network attack vector, low complexity, no privileges, no user interaction, unchanged scope, and high C/I/A impact.
Likely exposure
Organizations running affected Oracle Coherence versions are exposed if attackers can reach Coherence over TCP. Highest concern is for internet-reachable, partner-reachable, or broadly internal deployments where network segmentation is weak.
Exploitation context
The source states the vulnerability is easily exploitable by an unauthenticated attacker with TCP network access. The bundle does not show CISA KEV listing or cited evidence of active exploitation.
Researcher notes
No CWE, exploit details, or workaround specifics are included in the supplied bundle. Analysis is limited to Oracle's CVE description, CVSS vector, affected versions, and advisory reference.
Mitigation direction
Review Oracle's July 2026 CPU guidance for CVE-2026-60306.
Patch or upgrade affected Oracle Coherence versions per Oracle guidance.
Restrict TCP access to Coherence to trusted systems only.
Use segmentation and firewall rules to reduce reachable attack surface.
Prioritize externally reachable or business-critical Coherence deployments first.
Validation and detection
Inventory Oracle Coherence deployments and record exact versions.
Confirm whether affected versions are reachable over TCP.
Check whether Oracle's July 2026 CPU guidance has been applied.
Review access controls around Coherence network paths.
Monitor for unusual Coherence service access or takeover indicators.
